In carrying out the iinvention, there is provided a frame, denoted generally by the numeral 1, the trame comprising` a base 2 and a top 37 the top being va composite structure and includingI an upper member 4i, in the form of a plate7 and a lower member 5 in the form of a ringr. rrrlhe top 3 and the base 2 are connected bv securino'l elements 5, such as bolts (Figure 4),? tubular spacers 7 being?y mounted on the bolts. the spacers being interposed between the base 2 and the lower ring 5 (Figure 7) of the top 3.

Shafts 8 and 9 (Figures 1 and 12) are journaled in the top 3 and are provided with feed rolls 10 located above the upper plate il of the top 3. The shaft 8 is supplied with a driving means 113 ot any desired sort.

l'nner sha'its 12 are mounted to rotate in the upper plate or the top 3 and in the lower ring' 5 ofthe top. The shatts 12 prefijerably are dispo-sed in a circle, and shats 1e. alternatingl with the sl sits i2 are jeun naled in the parts dind 5 o' the rop 3. The

shatts 12 carry pinions 15 (F iguix 3) dismeshing (Figure 6) with the pinions 15 onV the shafts 12. Guter shafts 17 are journaled in the parts land 5 of the top 3, in radial alinement with the shafts 12. Finions 13 (Figure 3) are mounted on the shafts 17 and are located between the members e; and 5 of the top 3. The pinions 13 on the outer shafts l? mesh with the pinions 15 on the shaits 12, as shown in Figure l. Feed rolls 19 are mounted on the shafts 12 and cooperate with feed rolls shafts 17.

Passing; to Figure 4 it will be observed that the shaft 21 carries a beveled pinion 22 meshing' with a beveled gear 23 on a hori- Zontal shaft 24C journaled 'tor rotation in bearings 25 on the base 2. A pulley 2 6 is rotatably mounted on the shaft 24, but maj)Y be coupled to the shalt by a mechanism now to be described. rlhe pulley 26 a hub equipped with an end ratchet 23. A. rotat able member 29 is secured to the shatt- 24e. A pawl 30 (Figure 10) slides in the rotatable member 19 in a direction parallel to the sha 2-, the pawl being` advanced by a spring 35 housed within the member 29. rilhe pawl 30 has a beveled shoulder 3l (Figs ure 11).. A lever 32 (Figure 9)l is provided, and has beveled end `33 (Figure d). The lever 32 is 'ulcrumed 34, intermediate its ends, on the base 2. The lever 32 cooperates one end with a cam 3G attached'to a vertical shatt 37 journaled in the base 2 and in the upper plate l of the top 3. rThe shatt Vcarries an arm 33 (Figure l) located above the upper plate d oit the top rl`he arm 38 lies in the path of the material 39. as the material is Jed into the machine by the rolls 10. rlhe arm 33'has in extension 33 adapted to cooperate with top 69 on the plate 4 20 on thel of the top 3. A torsion spring 4G is connected to the shaft 3? (Figure 9) and is connected to the base 2. rlhe extension 89 on the arm 38 adapted to cooperate with the stop G9 to limit the rotation of the shaft- 37 under the action of the spring 40, 1when the material 39 is not in the machine.

As shown in Figure L4bearings 4l mounted on the base 2, and in the'betrings, a shaft 42 is mounted for rotation. fr pulley 43 is loose on the outer end of the shaft 42 butis adapted to be coupler` thereto. The pulley 43 has a ratchet 44. fr rotatable meinber 45 is secured to the shaft 42, the rotatable member 45 being constructed lilre the rotatable member 29 shown in Figure l0? A paWl 46 is mounted in the rotatable member 45 and is constructed like the paivl 3 hereinbefore described, the parivl being ada ted to cooperate with the beveled end 4f!" of a crank arm 48 on a shaft 49 mounted rocking movement in bearings 5o on the base rlhat end of the shaft 49 ivhi-"h is remet from the crank arm 48 carries a crank ari 5l (Figure united by a connection With a lever 53 (Figure 3) 'iiilcruuied inten mediate its ends on a bracket carried by the lower ring 5 of the top 3. The lever is disposed in the path of latch pivotally mounted at 55 on the reciprocati1 D hammer 57 of a stapling mechanism or like'fastening device.

The mechanisnrabove described pA for the coiling of the material into a The device includes means for the hoop after it has been coiled and vcned, and the ejecting means will nou.7 be described. Y

As shown in Figure 3, the shaft 42 is provided with a crank ufliercunto a pitman 59 (Figure is pivoted, the upper end of the pitman being pivoted at GO to a tubular slide 6l mounted for vertical reciprocation on a depending guide G2 carried by the upper plate 4 of the top 3. Adjacent to its upper end, the tubular slide 5l is provided With annular flanges G3, betr-reen vvhich the inner ends of levers 64 are mounted to roch, the levers being fulcrumed intermediate their ends, as at 65, on hangers 8G carried by the lower ring` 5 ofthe top 3. 1Il'ivectors 67, in the form of plungers, are pivotally mounted at 68 on the outer ends of the levers G4 and slid-e vertically in the constituent parts 4 and 5 of the top 3. [is Figure l will malte evident, the plunfrers or ejectors 6'? are located in a circu-. ference disposed between the feed Wheels i9 and 20, and are apted to push upwardly, the finished hoop, after th-e hoop has been coiled by the action of the feed Wheels or rollers i9 and 20.

The material 39 is entered between the feed rolls l0, as shown in Figure i, and is advanced because the shaft 8 and the corresponding feed roll l0 are rotated by means rovides a hoop of the mechanism shown at 11 in Fig. 5. rThe material 39 having been advanced, engages the arm 38 (Figure l) and rocks the shaft 37 (Figures 4 and 5), the spring 40 (Figure 9) being put under torsion. The cam 3G on the shaft Si' tilts the lever 32 out of the position of Figure lO into the position of Figure 9, and the lever 32 is disengaged from the shoulder 3l on the paivl 30 Whereupon the pavfl is moved to the left (Figure ll) and with the ratchet 28 on the hub 27 of the pulley 25 (Figure 4), thus coupling the pull y to 'ihe shaft 24, since the rotatable r ber 29 (Figure l0) which carries the paiv 30, is secured to the shaft 24. The shaft 24 new derives rotation from the pulley 26, and the beveled gears 23-22 (Figure 4) rotate the shaft 2l (Figures l, 3 and 8), the shafts l2 being rotated by Way of he pinions l5 on th said shafts, and the corresponding pinion on the shaft 2l, the interposed Wheels 16 exercising their obvious function. The pinions l5 rotate tie shaft l? (Figure l) by ivay of the pinions is (i the feed Wheels lf), and the shafts 17 rotating the feed wheels 20. The material 39 is drawn around in the form of a hoop by the feed rolls 1Q and 20. llalhen the material, having been formed into a hoop, no longer engages the arm 38 on the shaft 3?, the spring 40 imparts reverse rotation to the shaft 37 until the e: nsion 89 of the arm engages the stop G9 and disposes the arm 38 in the dotted line position of Figure l, in

of the next strip of material which i .ced by the feed Wheels l0.

i e shaft 3'? is inverselyv rotated by msaid` the cam 36 perg the lever 32 (Figardlv until the beveled t path of the beveer ou the paivl 30. "When the 29 is rotated, the beveled end 33 of er coacts With the shoulder 31 on the O and rctrects the paivl into the posif Figure l0, out of engagement with the ratchet 28 en the pulley 26, the pulley being uncoupled from the shaft 24, and the sl aft and the feed rolls lQand 2O coming ioop remaining stationary. The hammer 57 advances to the right in 3 aid fastens the ends of the hoop, t ie hammer advances, the latch 55 er the upper end of the lever 53. n, l oivever, the hammer 5'? moves to the in Figure 3, the latch 55 first tilts the c 5 and then passes clear of it, into the c noi down ,Q i lever is in 1 the 'ui-es l and 3), the shafts l2 rotating shoivn in Figures 3 and l. /VhenV on the pulley 43, thus coupling the pulley to the shaft 42. The shaft 42 then is rotated by the pulley 43, and the crank 58 on the shaft 42, together' with the pitman 59, raises and lowers the slide 6l (Figure 3), the levers G4 being tilted, and the plungers G7 being raised when the slide moves downwardly, the plungers ejecting the finished hoop from between the feed rolls 19 and 20. Then the stapling hammer 57 has carried the latch 55 far enough to the left to clear the lever 53, the shaft 49 is set free for rocking movement, and the arm 48 swings downwardly far enough so that its beveled end 47 is in the path of the shoulder on the latch or pawl 46, the latch or pawl being retract-ed,

and being moved out of engagement with the ratchet 44 on the pulley 43, the pulley being uncoupled from the shaft 42, and the shaft 42 coming to rest after the shaft has made one revolution and after the ejecting mechanism has exercised its oiiice.

What is claimed is l. In a machine for coiling material into a hoop, a plurality of inner rotary members supported for individual axial rotation, and located in an arc, and so positioned as to engage the inner surface of the material to be coiled, and a plurality of outer rotary members supported for individual axial rotation, and located in an arc, and so positioned as to engage the outer surface of the material to be coiled, the inner and outer members coacting to move the material to be coiled, in an arc, means for rotating the inner members and the outer members about their several individual axes, and hoop ejectors operating in the arc in which the material is coiled, and in a direction substan-v tially parallel to the axes of rotation of said inner and outer members, and mechanism for actuating the ejectors together.
